No harm, right? I just made it the year before last, and it hurt a little in the first few days. After that, it will be fine. Now that breast enhancement technology is so developed, as long as you choose a good prosthesis, there will be no problem. I did it in Weifang Boya Plastic Surgery Hospital. If you want to do it, I suggest you go to Boya. It is the most formal place in Weifang.
